Well, I think it should be posted on AITA on reddit.
So I have this friend, we used to hangout together at a pub, Tuesdays, Fridays, and Saturdays. We played Nägeln, Darts, or Chess. One time I was there alone, no one of the people I used to hangout with were there, so I played some cash game on my phone. When he came we exchanged greetings then he asked if I'm up to play a home game against him and his friends, I agreed. Then came one of the bridge days, weekens + May 1st a holiday, we started playing on Sunday afternoon. We had to ship in for snacks and drinks, the problem is that we played until Monday at 10 a.m. I finished with almost 3000 €, the "friend" by whom I was invited walked me down to take some breakfast, I paid for mine, he demanded thst I must pay for his, because I won around 3k, I was bewildered, I told him that I didnt invite him for breakfast, as a matter of fact I took a double espresso and a croissant. And that if he didnt have money to pay for his meal, i will gladly lend him money, he was upset. I was going to pay for his breakfast anyways, but when he started demanding it, I decided against it.
You can draw your conclusions, but many times when he won at Nägeln or Darts I bought him Laphroaig 4cl which costs 10 euros, but when I won he bought me a freaking Pfeffie, a peppermint drink that costs 2.5 €. At best case scenario it was a cheap a*& vodka for 4 €. I didnt care at thr time, never told him that, but i noticed it
